How much transmiission fliud does a TH350 hold when up to temperature? The owners manual says 2.5 Qts, this can't be right, after bringing the engine up to operating temperature and pulling the dip stick on the transmission there is nothing on the dip stick after I had put the above mentioned 2.5 Qts in. :confused: :confused:

If your servicing the transmission in the car. And only drop the pan it will take 4.5-5.5 quarts.

The tranny was out of the car and a shift kit installed with a 2500 stall converter added. So the tranny was dry including converter.

Are you running an external cooler, or the integrated cooler in the radiator? If you are, you'll also have to add enough to make up for any of the fluid loss from the lines/cooler during trans removal.

So, you didn't add fluid to the converter before installing it? :eek: Depending on the size of the converter, I add around a quart, or two, to my race converter before installation.

I don't remember exactly, but my dry transmission with a deep pan and 9 1/2 inch converter took about 10 quarts. That was also filling the cooler lines and an external cooler for the first time.

9-10 quarts if it was totally dry. The pan holds 2.5 to 3 quarts only. Don't run it too long with very little fluid in it or out it comes again.:eek:

TH350 Tranny Fluid Question

Guys:
So I just replaced the pan gasket on my TH350 due to a leaky gasket and after cleaning pan, replacing gasket, etc., I started putting fluid in. I only put in 3 qts (the guy at NAPA said at least 5...) and it is showing over full. I did run the car after the 3 quarts and cycled the gears too. Did I do something wrong?

Run the car through all the gears several times then recheck the fluid level. If it still shows over full then drain some out of the pan and recheck the level. Also, be sure the trans is warmed up because the fluid level will read different when it is cold.

Thanks for the reply. I will definitely warm it up more; I didn't do that, but I did run it through the gears 3 times. Will continue to do that, go for a drive, and check it.

Thanks again for helping a newbie!

If it was bone dry, it takes awhile to get it in the torque converter. Check it through the week. I swapped my th350 with a dry one last month & total fluid was around 9-9.5 qts..

I want to say 8.5 maybe for my 350 w/stock pan and a 9.5" converter.

the easiest way to drain some fluid from overfil is to take off a cooler line and put one of your empty quarts over each line,have a buddy stop and start the car.once you find witch end fluid comes out of you can drop the second empty quart.
a bone dry 350 should hold close to a case of oil. i put in 4 quarts.start car and shut doun after about 15seconds or so. add another 3 or so quarts and start car.then you can run car and add a 1/2 quart check and repeat.

Good info, but mine wasn't bone dry; it was full, but leaking (due to poor install by a major retailer with the golden touch) so I did it myself. So I guess just the pan holds about 3 quarts (which is about what I got out minus what went onto the cardboard).

On a side note: Can you drain the converter without removing the tranny? My chassis manual doesn't say.

Not entirely true, back in the day, before lock-up converters, there were 1/8" pipe plugs in the converters that we used to take out and let them drain on a service:cool:
